Carbon dioxide supercritical extraction is one application of the supercritical fluid extraction (SFE) process. SFE is a separation technology that uses supercritical fluid solvent for extraction.

Carbon dioxide is the most commonly used supercritical fluid, with other choices including ethanol.It allows you to create a pure, clean, quality oil that is safe to produce with little-to-no post-processing. Processes that use toxic solvents may require many hours to purge the solvent trapped in the oil.

• CO2 is the safest, and most efficient extraction method with the lowest long-term costs for manufacturing.
• It is important that the CO2 is a liquid in order to mix with the raw materials in order to strip the desired compounds during CO2 extraction.
• CO2 is natural which also allows for obtaining organic certification and reduces harmful emissions that are harmful to the environment.
